Abstract
Techniques are provided for mastering resources by assigning resources to mastery-eligible-sets. The resources that are assigned to a mastery-eligible-set may be mastered only at nodes that belong to the mastery-eligible-set. The membership of a mastery-eligible-set for a given set of related resources may be established based on which nodes have the highest affinity for the given set of related resources. Resource usage may be monitored, and the system may be periodically reconfigured, by changing membership of the mastery-eligible-sets, based on the usage information.
Claims28
A method for mastering resources, the method comprising:
- within a system that includes a plurality or nodes that have access to a particular resource, establishing a mastery-eligible-set for the particular resource;
- wherein the mastery-eligible-set includes two or more nodes of the plurality of nodes;
- wherein the mastery-eligible-set does not include all nodes of the plurality of nodes;
- and
- allowing the particular resource to be mastered only by a node that is a member of the mastery-eligible-set.
